Important Note: Microsoft strongly discourages downloading ISOs from torrent sites, unauthorized mirrors, or file-sharing platforms. These often contain malware, outdated Cumulative Updates (CUs), or modified binaries.
When downloading the ISO, you must choose the correct edition. Both editions are contained within the same ISO binary—the edition is determined by the product key you enter during installation.
